First Scientific Results from the VISTA Hemisphere Survey (VHS)
The first Galactic and extragalactic results from the VISTA Hemisphere Survey (VHS) are presented. The aim of the VHS is to carry out a near-infrared survey which, when combined with other VISTA public surveys, will result in coverage of the whole southern celestial hemisphere (~20 000 square degrees) to a depth 30 times fainter than the Two Micron All Sky Survey in at least two wavebands (J and Ks). The VHS vision includes a deep optical survey over the same area and this is now being realised with the VST surveys and the Dark Energy Survey, which has recently started. A summary of the survey progress is presented, with some follow-up results on low-mass stars and high-redshift quasars.
